Title: Dispositif pneumatique pour le deneigement des vehicules routiers
Inventor: CHARTIER ALBERT JR
IPC: B62D35/00
Filed: 2001-10-15
Abstract: L'hiver la neige s'accumule facilement sur les toits plats et immobilisés d es remorques et sur les boîtes de camion porteur. Le routier est tenu de déneiger son véhicule avant de s'engager sur le réseau routier. Le déneigement est une opération ardue et souvent dangereuse, de plus le toit des véhicules sont fragile et son souvent endommagé lorsqu'ils sont déneigés. En plus de la neige, la glace est encore plus difficile à enlever car il faut la briser avant de l'enlever.   Dans la présente invention une membrane extensible est tendue sur le toit du véhicule pour couvrir toute sa superficie. De Pair est poussé entre le toit du véhicule et la membrane, rendu étanche en étant ceinturé d'un cadre.  Par la pression pneumatique la membrane prendra la forme d'un ballon et la neige accumulée tombera de chaque coté du véhicule, de plus la membrane en prenant son expansion cassera la glace.
Patent CA-2361394-A1 (CA)
Title: Fiber-optic homodyne gyroscope
Inventor: KOPACEK ILJA
IPC: G01C19/72
Filed: 2001-10-22
Abstract: Most of the commercially available single mode fiber-optic gyroscopes work like this: a very short pulse of light from the laser is sent down the fiber. It first travels through the unidirectional coupler, then through the polarizer and then through the optical beam splitter/combiner which first splits the light beam and then recombines it after it passes clockwise and counterclockwise through one sensing loop. When the sensing loop is not rotating (moving) there is going to be no mutual phase offset of the clock and counterclockwise waves when they will recombine after passing through the beam splitter/combiner. When the sensing loop is rotating (moving) the above mentioned phases of clock and counterclockwise waves will be mutually offset. This mutual phase offset will produce a different interference pattern which will travel once again through the unidirectional coupler to the measuring equipment. This measuring equipment can then measure the degree of change in the interference pattern from which the speed at which the sensing loop (gyro) is rotating can be derived.

Title: Impact energy absorption member
Inventor: KARAKI TAKUYA
IPC: F16F1/366
Filed: 2000-12-15
Abstract: The present invention is an impact energy absorption member that is characterized by comprising a long member of fiber reinforced resin having a lengthwise direction and a thickness direction, wherein the ratio of the thickness t (mm) of the long member to the length L(mm) thereof is within the range of 1/11000 to 6/1000 as well as the direction of an external force is substantially in agreement with the thickness direction of the impact member.

The projections (14, 16) then engage with the internal surface of the duct to retain the duct on the neck portion (2, 3) and a good sealing contact is achieved about the sealing ring.  There is also provided a method of manufacturing such a duct joiner by moulding the joiner in at least two parts (21, 22) and joining side edges of the two parts together by complementary inter engaging formations (27, 28).
Patent CA-2365506-A1 (CA)
Inventor: JONES JOHN CLIFFORD
IPC: G09G3/36
Filed: 2000-03-02
Abstract: La présente invention concerne un dispositif à cristaux liquides nématiques bistables dont l'adressage est mis en oeuvre par application d'une forme d'onde de rangée à des électrodes de rangée successives d'une matrice x,y de pixels tandis qu'une de deux formes d'onde est appliquée à chaque électrode colonne. La forme d'onde présente une période de deux ou plusieurs intervalles de temps (ts), avec deux impulsions de courant continu (CC) à amplitudes opposées afin de provoquer une commutation dans un état sombre, et deux impulsions CC d'amplitudes opposées afin de provoquer une commutation dans un état lumineux. Les formes d'onde de données présentent la même période que les impulsions d'activation avec des impulsions CC d'amplitudes opposées et se combinent avec les impulsions d'activation afin de faire commuter le dispositif. Il est possible d'adresser le dispositif dans deux périodes de champ, un champ commutant à un état sombre, l'autre champ commutant à un état lumineux. Dans une autre réalisation, le dispositif peut être effacé à l'état sombre puis sélectivement commuté à l'état lumineux. Lorsque l'effacement est utilisé, la forme d'onde présente deux impulsions CC placées un court instant avant une commutation sélective afin de réduire la durée complète d'adressage. Il est possible d'utiliser des impulsions à tension nulle à l'intérieur des deux ou de plusieurs périodes d'intervalles de temps de l'impulsion d'activation et des formes d'onde de données, ce qui permet de réduire les tensions effectives aux pixels et d'augmenter le rapport de contraste.

Title: Fast optimal linear approximation of the images of variably illuminated solid objects for recognition
Inventor: ISHIYAMA RUI
IPC: G06V10/60
Filed: 2002-03-22
Abstract: An efficient computation of low-dimensional linear subspaces that optimally contain the set of images that are generated by varying the illumination impinging on the surface of a three-dimensional object for many different relative positions of that object and the viewing camera. The matrix elements of the spatial covariance matrix for an object are calculated for an arbitrary pre-determined distribution of illumination conditions. The maximum complexity is reduced for the model by approximating any pair of normal-vector and albedo from the set of all such pairs of albedo and normals with the centers of the clusters that are the result of the vector quantization of this set. For an object, a viewpoint-independent covariance matrix whose complexity is large, but practical, is constructed and diagonalized off-line.  A viewpoint-dependent covariance matrix is computed from the viewpoint-independent diagonalization results and is diagonalized online in real time.

IPC: A61B10/00
Filed: 2002-06-10
Abstract: A biopsy needle that is based upon an opening at the tip of the needle, not the side, that permits the entire sample to be cut from the patient yet has smooth sides to reduce injury to the patient when the needle is inserted. The needle of the invention has a coaxial inner needle or tube that allows the opening at the tip to be completely closed and the sample or specimen to be cut off at its point of attachment after insertion of the needle. The needle of the invention samples tissue in front of the needle as it is pushed forward, rather than scraping tissue from the edges of the needle track. In accordance with the invention, the coaxial inner needle can be withdrawn and the sample obtained without moving the outer needle or tube. Several samples can thus be obtained with minimal need for repositioning the needle avoiding pain, tissue damage and risks associated with such repositioning.
